STRIP CUTTING DEVICE Filed Dec. 2a, 1959 Gttorneg Patented Oct. 22, 1940 UNITED STATES PATENT OFFICE STRIP CUTTING DEVICE Raymond R. Ward, Cleveland, Ohio Application December 26, 1939, Serial No. 310,865

5 Claims.

' My invention relates to linoleum strip cutters and in particular to cutters which may be used to utilize the unused pieces of linoleum which are usually discarded.

The means for utilizing these waste pieces is the main object of my invention.

' Still another object is to recut strip linoleum to smaller widths for trims and insets.

These and other objects may be noted from the following specification and its accompanyingv illustrations, in which:

Fig. 1 is a top plan view of the device.

Fig. 2 is a side elevation of Fig. 1.

Fig. 3 is an end elevation.

Fig. 4 is a sectional view on lines 4-4 of Fig. 1.

Again referring to the illustrations; a U-shaped base It! is recessed or slotted as at H the full length of said base. A plurality of apertures l2 are provided adjacent each end of said base and are spaced at fixed or desired intervals as illustrated in Fig. 1 specifically, the top rail Illa, of the U-shaped base l0 being shorter than the bottom rail lb of said base, the projecting outer ends I3 and I3a of said base being shouldered at I4 and 14a toform a stop.

A plurality of bores or recesses l5, l6 and I1, through the top rail Illa, retain balls or bearings l8 therein which are held in position by flexible spring covers I9 pivoted at 20 on the top surface of the top rail Illa. A bore or recesses 2! through the bottom rail [0b also retains therein a ball or hearing I8a which is secured therein by a spring cover 19a pivoted at 2011. on the bottom surface of the bottom rail lllb of the base In.

An adjustable laterally sliding guide 22 is mounted within the recess ll between the rails, pins 23 securing said guidein the position desired when apertures 24 in the opposite ends of said guide register with apertures l2 in the bottom rail lllb of the base It! as shown in Fig. 1.

A groove 25 in the front surface and adjacent one end of the bottom portion lllb of the base H] has mounted therein a separating guide 26 secured to said bottom base portion Illb by a set screw 21.

Inwardly therefrom is an angular slot 28 in the front surface of said base portion [0b, while diagonally therefrom is a second angular slot 29 in the top portion I0a.- of the base Ill, said slots registering upon a diagonal plane.

A very thin cutting blade 30 is mounted within the angular slots 28 and 29 with the cutting edge 30a towards the center of the device. A pair of blade mounting or holding plates 3| and 32 are secured to the top and bottom portions Illa and i012, over the blade 30, by pairs of set screws 33 and 34, for the holding plates 3! and 32.

An adjustable guide 35 is mounted within a slight recess 36 in the top surface of the top- 5 portion I lla, said guide is slotted at 35a. for a sliding adjustment when the set screw 3! is released. Y

A stepped roller 38 is mounted on a pin 39 and is secured in place to the underside of the out- 10 wardly projecting end of the guide 35 by a nut 40 screwed upon the threaded end of said pin.

A mounting block 4| may be used to secure the device to a table or the like when. in use.

In operation, the linoleum strip 42 is inserted 15 within the recess H from the right side and drawn along therein past the spring pressed bearings or. balls l8 and [8a, which act as tensioning devices on the linoleum strip, until its forward edge contacts the blade edge 30a.

The inner edge of the linoleum strip 42 is pressed against the laterally sliding guide 22 which has been adjusted to the desired width by registering certain of the apertures 24 at each end of the slide guide 22 with other apertures I2 at each end of the bottom portion Illb of the base ID. The pins 23 secured therethrough hold the slide guide 22 in proper alignment with relation to the linoleum.

The linoleum strip 42 is drawn forward from right to left, theblade 30 cutting through the strip 42 which is parted by the separation guide 26.

I claim:

1. A strip cutting device comprising a U- shaped member forming upper'and lower rails with a space between the same, an adjustable guide mounted between the rails, spring pressed tensioning balls in the upper and lower rails, a cutting blade mounted on the rails, and a separating guide behind the cutting blade.

2. A strip cutting device comprising a U- shaped member forming upper and lower rails with a space between the same, an adjustable guide mounted between the rails, spring pressed tensiom'ng balls in the upper and lower rails, a cutting blade diagonally mounted in recesses in the face of the rails and a separating guide behind the cutting blade.

3. The combination stated in claim 1, said blade being held in place by blade holding members mounted on the rail faces.

4. The combination stated in claim 1, and a further guide mounted in a recess in the upper surface of the device and having a roller extending outwardly past the face of the rails and engaging the outer edge of the material.

5. A strip cutting device comprising a U- shaped member forming top and bottom rails, the top rail being narrower than the bottom rail, a plurality of apertures formed in each end of the upper surface of the bottom rail, a laterally movable guide having holes in its respective ends and a pin passing through a hole in the end of the guide and intoone of the apertures of the bottom rail to hold the guide in a selected position, spring pressed tensioning devices mounted in both the top and bottom rails, a cutting blade 5
